What does modem (110) represent?

Modem (110) denotes a legacy data transfer speed of approximately 110 bits per second used in early dial-up and teletype communication systems.

What is STS3 (payload)?

STS3 (payload) refers to the user-data portion of a SONET STS-3 frame, indicating the available bytes for carrying client traffic within a high-speed optical transport channel.

Why is the conversion result so small?

Because modem (110) is a very low bit rate compared to the high-capacity STS3 payload rate, the conversion yields a very small number, reflecting the large difference in scale.

Examples

Converting 10 modem (110) units results in approximately 7.3169433801618e-6 STS3 (payload).
Converting 1000 modem (110) units results in approximately 0.00073169433801618 STS3 (payload).

Common Use Cases

Translating low-speed legacy modem data rates for network capacity evaluation in telecom infrastructure.
Comparing historical dial-up or teletype line speeds with modern SONET payload capacities.
Planning capacity and provisioning for carrier backbone OC-3 circuits using equivalent legacy data rates.
Conducting performance benchmarking and protocol testing across vintage and current telecommunications devices.
Documenting or emulating old telemetry or serial data communications.

Tips & Best Practices

Use the tool to assist in telecom network engineering when integrating legacy systems with modern infrastructure.
Consider the nominal nature of the modem (110) speed and very small conversion results when interpreting outputs.
Account for the exclusion of overhead bytes in STS3 payload values when planning capacity or billing.
Utilize example conversions to verify calculations and better understand unit relationships.

Limitations

The modem (110) speed represents a very low and nominal bit rate, resulting in extremely small converted STS3 payload values.
STS3 (payload) measurements exclude overhead bytes, so payload capacity may vary slightly depending on framing and protocol overhead.
Conversion results may not be practical for direct data volume comparisons due to the large difference in scale between units.
